Diabetes query

My mother in law had an emergency admission to hospital with Diabetic ketoacidosis .
We await results of genetic testing to see if her T2 diabetes is really LADA ( latent autoimmune diabetes).

She has lost a lot of weight as her body has been in a catabolic state for a while , but she's doing well and is out of HDU into a receiving ward .

However I'm really concerned as her diet in hospital has not been a diabetic one , it's a standard elderly diet to address weight loss and features such wonders as Jam sponge and custard ( after which her blood sugars spike to 24) .
Dietician visited today to advise this is the procedure they are taking.

I can't understand why there isn't a diabetic based diet which can address weight loss ( fat anyone? )
.with blood sugar on a daily roller coaster surely this will make the diabetes more chronic ?

Has anyone else experience of this logic ?

Tagging @Midnattsol in case there is an evidence base

 

I don't think jam and sponge indiscretions over a few days will have any long term impact, however barmy they may be at the time. The NHS, as we all know, is falling apart and it does not surprise me that there is no sensible dietetic management but the important thing is to have a regular diet with the right carbohydrate content over a period of months and years at home.

 

Thanks @Jonathan Edwards . I've no doubt when she gets home her diet will be better and she will have much better monitoring in the community than she has had to date. Its the 4-6 weeks of jam sponge and custard that's a bit concerning.

 

Thanks @Midnattsol .
Glad that I am not going completely mad on logic of this !
My daughter was given fat shots to build her up ( they are pretty awful ) . I suspect cholesterol is on higher side ( came down when she spent 2 weeks in Sweden with her sons family over Christmas as they don't eat sugary snacks... )

I suspect there's a balance to be found between quality of life and health .
We've been told she won't be the same woman that comes home , so we probably have to be realistic over what her wishes will be for the years she has left .
